#xss

The application suffers from an unauthenticated stored XSS vulnerability that results in stored JS code and authentication bypass. The issue is triggered when input passed to the 'username' parameter is not properly sanitized before being returned to the user. This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected site.

Quanos "SCHEMA ST4" example web templates in version Bootstrap 2019 v2/2021 v1/2022 v1/2022 SP1 v1 or below are prone to JavaScript injection allowing a remote attacker to hijack existing sessions to e.g. other web services in the same environment or execute scripts in the users browser environment. The affected script is '*-schema.js'.

The login password of the web administrative dashboard in Arcadyan Wifi routers VRV9506JAC23 is sent in cleartext, allowing an attacker to sniff and intercept traffic to learn the administrative credentials to the router.

The csaf_provider package before 0.8.2 allows XSS via a crafted CSAF document uploaded as text/html. The endpoint upload allows valid CSAF advisories (JSON format) to be uploaded with Content-Type text/html and filenames ending in .html. When subsequently accessed via web browser, these advisories are served and interpreted as HTML pages. Such uploaded advisories can contain JavaScript code that will execute within the browser context of users inspecting the advisory.

Delta Electronics DX-2100-L1-CN 2.42 is vulnerable to Cross Site Scripting (XSS) via lform/urlfilter.

Certain Linear eMerge E3-Series devices are vulnerable to XSS via the type parameter (e.g., to the badging/badge_template_v0.php component). This affects 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e.

Nortek Linear eMerge E3-Series 0.32-08f, 0.32-07p, 0.32-07e, 0.32-09c, 0.32-09b, 0.32-09a, and 0.32-08e were discovered to contain a cross-site scripting (XSS) vulnerability which is chained with a local session fixation. This vulnerability allows attackers to escalate privileges via unspecified vectors.

HTML sanitizer is written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags, attributes and values. In versions prior to 1.5.0 or 2.1.1, malicious markup used in a sequence with special HTML CDATA sections cannot be filtered and sanitized due to a parsing issue in the upstream package masterminds/html5. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer. The upstream package masterminds/html5 provides HTML raw text elements (`script`, `style`, `noframes`, `noembed` and `iframe`) as DOMText nodes, which were not processed and sanitized further. None of the mentioned elements were defined in the default builder configuration, that's why only custom behaviors, using one of those tag names, were vulnerable to cross-site scripting. This issue has been fixed in versions 1.5.0 and 2.1.1.

The Image Hover Effects Ultimate plugin for WordPress is vulnerable to Stored Cross-Site Scripting via several values that can be added to an Image Hover in versions 9.8.1 to 9.8.4 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. By default, the plugin only allows administrators access to edit Image Hovers, however, if a site admin makes the plugin's features available to lower privileged users through the 'Who Can Edit?' setting then this can be exploited by those users.
